will be hereinafter described in detail, and this ulated, The valve member is also .provided with 55 member 2 I.

as the valve member 2| is oscillated to the left in Figure 2, by the pressure of 'gases generated in the chamber |I, through the medium of a screw or similar stop 55, the plunger is moved to place the spring 53 under compression. This stored up energy in the spring 53 tends to return the valve member to its initial position of rest, after the same has been moved to thel left or .in a counter-clockwise direction in Figure 2 by pressure of the gases generated in the chamber II. v

Leading'from the power take-off device and connected to the pipe 28,'there is a pipe line 60v which terminates at a coupling 6|, which in turn is carried by a suitable receptacle 62. This receptacle carries a volume of cooling fluid 63 which is preferably water, and leading from the receptacle 62 there is a pipe line 64 which is passed around the receptacle 62 to form a series of coils 65 from which the pipe line 6l leads to `a point 66 on 'the power take-off device, as best illustrated in Figure l3.

Leading from the receptacle 62 there is a pipe line 61 which includes a check valve 68, and this pipe line discharges 'into a .receptacle 69 having an outlet '10 controlled by a valve '|I, which receptacle also has a drain-off cock 1 2.

Leading from the coupling 6| there is a pipe line which has a section 90 therein which is of considerably reduced internal diameter to `form a constricted passage in the pipe line 80.

This pipe line 80 is formed with a series of coils 9| and is connected as at 92 to the power takeoff device, as .best illustrated in Figure 3.

The device operates in the following manner.

Lets assume that the device iscold and that there is no stored pressure in the receptacle 69. Uponstarting of the internal combustion motor, and upon firing of the charges in the ring chamber I| thereof, the pressure will pass upwardly through the pipe section I3 and be discharged from the nozzle I8. When the gases are discharged from the nozzle I8 they vimpinge upon the wall'24 and oscillate the valve 2| in a counter-clockwise direction. This movement of the valve 2| uncovers the opening 25 and permits the gases to pass from the chamber 22, through the passage 25 and through the pipe line 60 to the receptacle 62, Upon attaining a predetermined pressure in the receptacle 62, said pressure forces open the check valve 68 and the gases pass to the receptacle 69 where they may be stored under pressure for use, they being taken from this receptacle through the /pipe line 10. 'I'he pipe line 60 is of larger diameter than the remainingl pipe lines which construction insures the passage of the gases to the receptacle 62, which latter will,

in all installations, be located at a-level below that of the motor cylinders'.

As the pressure builds up in the receptacle |52` the cooling iluid is forced through the pipe line 64 and the several coils B5 thereof, and is discharged into the housing I directly upon the valve member 2| to prevent overheating thereof. This cooling fluid accumulated in the upper part of the housing 5 is, by reason of the pressure in the receptacle 62, forced outwardly through the pipe line 92 and'through a check valve |00 into the receptacle 62. This last mentioned action, however, takes place only when there is no pressure being introduced into the pipe line '60. When the valve member 2| is moved to the left in Figure 2, the spring 53, by reason of engagement of the stop 55 with the plunger 52, is placed under pressure so that as the pressure in the ring chamber is reduced, this spring 53 may push forwardly the plunger 52 to move the valve memperature rising suiiiciently high to render the device inoperative.

While the invention has been illustrated in its preferred form it is to be understood that it is not limited to the specific construction'shown and that it may be practiced in other forms without departing from the spirit thereof.
